Description

A horizontal biological fermentation device

technical field

The utility model relates to the field of wine fermentation and brewing, in particular to a horizontal biological fermentation device.

Background technique

Fermentation devices are widely used in dairy products, beverages, bioengineering, pharmaceuticals, fine chemicals and other industries. Existing fermentation devices can be used for anaerobic fermentation or aerobic fermentation. The fermentation process is a bacteria-free and pollution-free process, so Fermentation units adopt aseptic systems to avoid and prevent the contamination of microorganisms in the air. During the fermentation process, with the growth and reproduction of microorganisms, under the action of microbial enzymes, the starch, protein and other substances in the raw materials are hydrolyzed, causing a large amount of ethanol, organic acids and esters to gradually deposit under the action of gravity. The CO2 and low-boiling substances produced tend to accumulate in the upper layer as the fermentation temperature increases.

A study compares the physical and chemical indicators of the upper, middle and lower layers of the single-port pit in the solid-state fermentation pit, and found that in the same fermentation period, in terms of acidity: lower layer > middle layer > upper layer; in terms of moisture content: lower layer > middle layer > upper layer; in terms of starch content : upper layer > middle layer > lower layer. It shows that in the same pit, the fermentation situation of the lower layer is better than that of the middle layer, and the fermentation situation of the middle layer is better than that of the upper layer, which reflects the fermentation process and fermentation level. At the same time, the physical and chemical indicators of the upper, middle and lower layers of the single-hole pit pool and the central fermented grains found that except for the upper fermented grains, the fermentation of the middle and lower layers was better than that of the central fermented grains. The main reason is that the fermented grains by the wall are fully in contact with caproic acid bacteria and other functional bacteria of the pit mud, which makes the fermentation of the fermented grains by the wall more sufficient and the aroma production is more ideal. However, because the upper grain glutinous rice grains are not in too much contact with the pit mud, the advantages are not obvious, which fully shows that the rapid and stable reproduction and fermentation of functional microorganisms in the grain grain glutinous grains is of great significance to the improvement of the quality of Luzhou-flavor liquor.

The research shows that the physicochemical indexes and microbial contents are different between different levels of fermented grains at the same fermentation period in the same cellar.

Therefore, in traditional mud pits, the upper, middle and lower layers of grain glutinous rice contain different water content, resulting in different concentrations of key substrates such as ethanol, organic acid esters and dissolved oxygen. The growth rate of microorganisms in the pit was significantly faster than the growth rate of the microorganisms in the center of the pit, resulting in inconsistent fermentation process of grain grains in different parts of the mud pit, and at the same time, resulting in a decrease in the amount of distilled liquor in the later distillation process due to the different physical and chemical properties of grain grains.

It can be seen that one of the problems to be solved in this solution is that there is a dead angle inside the container due to uneven stirring by the agitator, resulting in differences in local raw material fermentation.

In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, because the applicant has studied a large number of documents and patents when making the present utility model, but the space limit does not list all the details and contents in detail. The present invention does not have the features of the prior art, on the contrary, the present invention already possesses all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art.

Effect.

According to a preferred embodiment, the above-mentioned fan blades 300 arranged along the radial direction of the accommodating portion 100 are not less than one axially arranged along the accommodating portion 100 . The advantage of the scheme of setting up multiple sets of fan blades 300 is that firstly, the divisional adjustment of the stirring opening time is realized. Taking the two shaft rods 200 that are placed on the upper and lower layers as an example, the fan blades 300 located on the upper layer are used for stirring. Substrates generally located in the upper layer and part of the middle layer, and the fan blades 300 located in the lower layer are used to agitate the substrates generally located in the lower layer and part of the middle layer. In the first time, the fan blade 300 of the upper layer is turned on and the fan blade 300 of the lower layer is closed, so that the substrates of the upper layer and the middle layer are mixed, and the fermentation uniformity of the two is consistent, while the substrate of the lower layer continues to be more stable because there is no stirring. Fermentation is carried out with high efficiency; in the second time, the fan blades 300 of the lower layer are turned on and the fan blades 300 of the upper layer are closed, so that the substrates of the lower layer and the middle layer can be mixed, so that a large number of microorganisms that multiply in the lower layer in the first time It can be mixed and sent to the middle layer, so that the number and rate of microbial reproduction in the middle layer are also greatly increased, and then the upper fan blade 300 is turned on in the next stage, so that the middle layer and the upper layer with the increased number of microbial reproduction are mixed, and finally the upper layer of the microorganisms reproduces. The quantity and speed have also been increased accordingly, which in general has accelerated and evened out the fermentation of each level. This scheme actually takes advantage of the characteristics of better fermentation conditions in the lower layer and a large number of microorganisms produced. By exchanging fermentation substrates with the upper space step by step, the microorganisms in the lower layer can be gradually lifted to the upper layer while balancing the fermentation effect. space, allowing the fermentation process to achieve fermentation uniformity without sacrificing fermentation efficiency. While the traditional single-stage stirring method roughly achieves the uniformity of substrates at different levels, it sacrifices the advantage of higher fermentation efficiency in the lower space, so that the substrates at each level are fermented in the lower layer. The time is very short, and the fermentation is fragmented. It is difficult to establish a good fermentation foundation, which eventually leads to a relatively long fermentation cycle and slow efficiency. This scheme also has an advantage in that it reduces the stirring output power. Compared with the single-stage, larger and stronger stirring mode, this scheme adopts distributed multi-stage stirring to achieve low single-stage stirring output power. On the basis of objectively reducing part of the power consumption expenditure, in fact, the impact of tangential force on fungi is also alleviated to a certain extent. Because the output power is reduced and the rotational torque is reduced, the tangential force caused by the rotation is reduced, and the impact on fermentation is finally reduced. Secondly, the method of opening by time is also beneficial to the bacteria in the interval where the stirring is not turned on. kind of recovery. Using the conventional single-stage stirring method, the mixing effect of the substrate near the shaft 200 is also relatively limited. Since this part is far away from the pit mud of the tank wall, the fermentation condition itself is poor, and the existing solution cannot be used well. With this solution, the substrate in the middle layer actually becomes the upper layer or the lower layer relative to the shaft 200 arranged above or below it, which is beneficial to take out the substance in the middle layer and improve the fermentation of this part. . The above-mentioned component that controls each shaft 200 to be turned on or off alternately in different periods may be a controller, which is connected to the power unit 400. The controller may be composed of various types of mcu chips or single-chip computers, such as various selections of STM32.
